Dark photon searches with atomic transitions

Journal of High Energy Physics, 2019
Dark matter could be made up of dark photons, massive but very light particles whose interactions with matter resemble those of usual photons but suppressed by a small mixing parameter.

Toy models of Universe with an Effective varying $\Lambda$-Term in Lyra Manifold [PDF]

, 2014
We are interested by the study of several toy models of the Universe in presence of interacting quintessence DE models. Models are considered in the cosmology with an Effective varying $\Lambda$-Term in Lyra Manifold.

Entangling Higgs production associated with a single top and a top-quark pair in the presence of anomalous top-Yukawa coupling

Journal of High Energy Physics, 2017
The ATLAS and CMS collaborations observed a mild excess in the associated Higgs production with a top-quark pair t t ¯ h $$ \left(t\overline{t}h\right) $$ and reported the signal strengths of μ tth ATLAS  = 1.81 ± 0.80 and μ tth CMS  = 2.75 ± 0.99 based ...

Dark confinement-deconfinement phase transition: a roadmap from Polyakov loop models to gravitational waves

Journal of High Energy Physics, 2021
We explore the confinement-deconfinement phase transition (PT) of the first order (FO) arising in SU(N) pure Yang-Mills theory, based on Polyakov loop models (PLMs), in light of the induced gravitational wave (GW) spectra.

Probing the dark sector through mono-Z boson leptonic decays

Journal of High Energy Physics, 2018
Collider search for dark matter production has been performed over the years based on high p T standard model signatures balanced by large missing transverse energy. The mono-Z boson production with leptonic decay has a clean signature with the advantage

Phenomenological study of hadron interaction models [PDF]

, 2001
We present a phenomenological study of three models with different effective degrees of freedom: a Goldstone Boson Exchange (GBE) model which is based on quark-meson couplings, the quark delocalization, color screening model (QDCSM) which is based on ...

Phenomenological model of visual acuity [PDF]

Journal of Biomedical Optics, 2016
We propose in this work a model for describing visual acuity (V) as a function of defocus and pupil diameter. Although the model is mainly based on geometrical optics, it also incorporates nongeometrical effects phenomenologically. Compared to similar visual acuity models, the proposed one considers the effect of astigmatism and the variability of best

AdS/QCD Phenomenological Models from a Back-Reacted Geometry [PDF]

, 2006
We construct a fully back-reacted holographic dual of a four-dimensional field theory which exhibits chiral symmetry breaking. Two possible models are considered by studying the effects of a five-dimensional field, dual to the $q\bar{q}$ operator.

Measurement of D 0 − D ¯ $$ {D}^0-\overline{D} $$ 0 Mixing Parameters Using Semileptonic Decays of Neutral Kaon

Journal of High Energy Physics, 2020
We propose a new method to extract D 0 − D ¯ $$ {D}^0-\overline{D} $$ 0 mixing parameters using the D 0 → K ¯ $$ \overline{K} $$ 0 π 0 decay with the K ¯ $$ \overline{K} $$ 0 reconstructed in the semileptonic mode.

Long-lived sterile neutrinos at the LHC in effective field theory

Journal of High Energy Physics, 2021
We study the prospects of a displaced-vertex search of sterile neutrinos at the Large Hadron Collider (LHC) in the framework of the neutrino-extended Standard Model Effective Field Theory (νSMEFT).
